Background: Acute transverse myelitis (ATM) in patients with no history of central nervous system (CNS) demyelinating disease may be idiopathic or herald the development of neuromyelitis optica spectrum disorder (NMOSD) or multiple sclerosis (MS). NMOSD may differ from MS in pathogenesis, prognosis and response to treatment, and radiological features at the first presentation of ATM that distinguish between NMOSD and MS would be desirable
Background: Neuromyelitis Optica (NMO) and its spectrum disorders (NMOSD), which include recurrent transverse myelitis (rTM) and recurrent optic neuritis (rON) are demyelinating diseases of the central nervous system (CNS).
In a subgroup of patients with neuromyelitis optica (NMO), a severe inflammatory demyelinating disorder of autoimmune origin characterized by recurrent attacks of optic neuritis and longitudinally extensive transverse myelitis, a parainfectious pathogenesis may play a central role.
